"S'pose you go out on the edge of the timber and larn for yourselves."

The lads followed the suggestion. Looking off in the direction of the Wind River Mountains, it seemed to them that tens of thousands of cattle were browsing among the foot-hills and on the grassy plain, while many more must have been beyond sight. This was one of the choicest regions of Wyoming, so widely celebrated for its grazing facilities.

It was an impressive sight, and the boys, each of whom was provided with a good spy-glass, surveyed the scene for some minutes in wondering silence. The cattle were several miles distant, and seemed to be brown, undulating hummocks of dirt, kept in constant motion by some force beneath. On the outer fringe they were more scattered, but were constantly moving, as if the pasturage was so excellent that they were continually tempted to give up that which was good for that which looked better.

"Are they left wholly to themselves?" asked Fred, as the youths came back to where the guide was saddling his pony.

"No. There are always two or three men looking after them. I seed Bart Coinjock, one of our own cowboys, 'tending our animals, and he told me to take my ch'ice from the lot. You mustn't forgit that we're purty close to the Wind River Injin Reservation, where the Government has several tribes under charge."

This was news to the boys. Hazletine explained that a large tract of land to the northwest and close to the mountains had been set apart some years before by the United States Government for exclusive occupancy by several tribes of Indians. They owned the land, and no white man had the right to intrude upon them.

In the Southwest, where the Apaches were placed on reservations, there had been the most frightful trouble, for those Indians are the worst in North America. All our readers know how many times the fierce Geronimo and a few of his hostiles broke away from their reservation, and, riding swiftly through Arizona and New Mexico, spread desolation, woe and death in their path. Not until Geronimo and his worst bucks were run down in old Mexico and transported bodily to the East was the danger to the Southwest terminated.

Nothing of the kind has taken place in Wyoming, Montana, the Dakotas and other reservations further east, but there is always a certain number of malcontents on the reservations who cause trouble. They steal away unnoticed by the authorities, and engage in thieving, and, when the chances are favorable against detection, commit graver crimes.

"That Injin that come into the timber last night was a sort of dog Injin that had come down from the Wind River Reservation to find out what he could steal."

The boys looked at each other in astonishment. They had made no reference to the visitor in the hearing of the guide, and could not understand where he had gained his knowledge. He noticed their surprise, and smiled.
